My 2007 LWB is going into the dealer for alignment tomorrow that is required after they replaced a strut in the back. The inside of both back tires that I took off and replaced with Michelin MXM4 were chewed to zero. I also put on new Michelins for the front. It rides very well, but I suspect that the "chewing " will continue if the alignment is not done properly. Thanks so much for all the info on the alignment specs. I will certainly be on the lookout for numbers that are not good.
